Audi A3

Audi announced three engines for the European market, 1.8- and 1.4-liter gas engines and a 2-liter diesel, all turbocharged. The 1.8-liter represents a downsizing from the current 2-liter, which should enhance fuel economy. Audi says these engines are all new, suggesting even the 2-liter diesel has been updated.
